1. Q: What test we will do before the machine leave factory?

A: Before machine leave factory, our engineer will mainly test the following 3 parts.

(1) Test the currency to be standard

(2) Test the demagnetization effect to be standard

(3) Test the noise, <85DB within one meter.

2. Q: How to operate the bearing heater?

A: Each bearing heater is with a operating manual, operating video is also available.

3. Q: How to guarantee our machine to be safe?

A: Bearing heater raw material & technology

(1) Fine copper coils, more heat insulation

(2) -10℃~400℃ insulation double glass envelope technology

(3) Electrical accessories are from Schneider

(4) Temperature -50℃-300℃ epoxy rods platinum thermal resistance,better magnetic properties

(5) Fully enclosed insulated coil

(6) E multilayer fiber ribbon, F grade epoxy insulating paint, multiple protection

(7) Special processing technology makes the radiation and noise to be minimum

(8) WTR brand temperature-resistant insulated gloves

(9) Each WTR bearing induction heater passed the CE, ISO9001, EMC,FCC.

4. Q: How about the operation precautions for safe?

(1) Bearing induction heater will produce an induction magnetic field which will influence or weaken the effect of the medical device such as pacemaker or hearing-aid, thus it will hurt health. Please do not operate the machine or stay within 5m away from the machine when wear such device.  

(2) Do not operate the induction heater in area existing explosion hazard.

(3) It is very important to conduct correct maintenance and handling. It will cause machine fault or have personal injury if operate out of user manual.

(4) Sensitive electronic equipment(such as mobile, watch, computer) will be influenced by the magnetic field, do not use them around the heater.

(5) Check whether the power and voltage are accordance with the heater nameplate, confirm the ground connection is good.

(6) Avoid touching the heated bearing directly, please use high temperature resistant gloves to carry the bearings.
